| 摘 要： | 对于首部式开发的水电站,其尾水系统水头损失直接关系到长期运行的经济效益。本文应用计算流体力学技术(CFD)对官地水电站尾水系统局部布置与结构体型进行数值模拟,开展三维流场计算与分析,得到其水头损失和流态,确定设计方案;然后进行模型试验,并对比分析数值计算和模型试验结果,证明三维流场计算结果的可靠性。采用三维流场计算可进行方案对比及体型优化并得出较优的尾水(引水)系统体型,可以为一些无法进行模型试验的工程提供设计依据。

| Abstract: | The long-term economic benefits of a hydropower station are directly affected by the tailrace system head loss.In this paper the up-to-date CFD（Computational Fluid Dynamics） technology is employed to simulate Guandi Hydropower Station tailrace system.By the results of head loss and flow field characteristics,the optimized design solution is chosen.Then the model test and comparison of numerical simulation data and model test data are carried out,which offer a scientific gist for engineering designs. |
